It is not "Braqhminical Arrogance" but "Brahminical Ignorance". These so-called Brahmins who meted out this disgusting treatment to Ravi's family should read these: "He in whom good conduct is manifest, is a Brahmin and in whom this is absent, treat such as Shudra". Mahabharata III.180.27 "It is tapas(austerity and penance) which makes one a Brahmin and not his birth"-Srimad Bhagavatham
"Not study, not learning is the cause of Brahmin status. Conduct is the basis..." Mahabharata III.312.106
